Remedial program is given to the students who do not pass the minimum criteria of learning result. Based on the âKTSPâ Technical guidance evaluation in 2008 and 2009, generally teacher only gave retest to the student who didnât pass the examination, without giving any treatment to pass the learning outcome which was not pass before. It happened because there wasnât enough time to do this program. The solution was by using learning social media Edmodo which can be accessed online, so the students can do remedial program whenever and wherever they want without preparing remedial time at school. So, the Chemistry teachers in Kabupaten Solok was trained to use edmodo for remedial program. Besides, this media was also used for online teacher forum. This training was evaluated through questioner about practicality of social media edmodo for remedial program and online teacher forum. The result was analyzed by Kappa Cohen Formula with the value of k is 0,7, it means has high practice value.

Modules are one of the learning materials that can be used in the learning process. Modules compiled based on guided inquiry learning syntax and integrating experimental activities that will be able to improve students science process skills. This study aimed to produce a reaction rate module based on guided inquiry integrated experiments and valid student science process skills and practical use in senior high school  chemistry learning. The type of this research was research and development (R & D) and the development model used was the 4-D model which consists of four stages: (1) define, (2) design, (3) development, (4) desseminate. This research was limited to the validity and practicality test. The validity test was carried out by 5 experts and limited trials to reveal the practicality done at SMAN 1 Lubuk Basung. The research instrument used was in the form of a validity and practicality questionnaire which was analyzed using kappa moment (k) Data analysis showed that the average moment of kappa validity was 0.84 with a very high validity category. The average practical kappa moments from teachers and students were respectively 0.83 and 0.85 with a very high practicality category. These results were also supported by the analysis of students answers in answering critical questions, exercises, prelab questions, postlab questions, and worksheets in modules, with an average value of 90.2. Based on the results of the study it can be concluded that the guided inquiry integrates experiments and science process skills on based reaction rate topic are valid and practical used for chemistry learning in senior high school.

Vaccine sequence of Neuraminidase BTB from previous research was studied by using swiss model server. Protein template was gotten from RSCB database by comparing the vaccine sequence with PDB database. HTY protein was used as a template for this vaccine. Template had 0.00e-1 E value, and 97% identity. The protein vaccine that has been modelled by swiss model had good quality as immune inducer. Base on ramachandran plot analysis, protein model 1, 2, and 3 have amino acid residues in favoured region higher than 70%. They are 82,0% and 78,2%. Model 1 has the lowest non glysine amino acid residues in disallowed region area, that is 0%. 3D Structure of vaccine had 2086 hits of similarity with database on NCBI Key words: comparing modelling, H5N1 vaccine, swiss model

AbstractThis study was conducted to determine the effectiveness of Children Learning In Science (CLIS) model using PhET simulation to reduce students misconception on hydrostatic pressure in SMPN 7 Pontianak.Â This study was quasiÂ pre-experimental design with one group pre-test post-test design. The population of this study was ninth gradeÂ students in SMPN 7 Pontianak. Intact group random sampling was used that involving IX F. the average decrease of student misconceptions were 38,03% with significant conceptual change by Mc Nemar test ( ). There was significant conceptual change after remediation by apply CLIS model using PhET simulation to reduce students misconception on hydrostatic pressure. Result reveal that the effectiveness level was 0,67 (medium). This research is expected to be used as an alternative remediation activities to reduce misconception in learning process and improve studentâ€™s learning outcomes.Â Â Keywords: Misconception, CLIS, PhET, Hydrostatic Pressure

The concept is an understanding of an individual or a group of people who is expressed in the form of a meaning that produces knowledge in the form of theories, principles and laws. Conception is a person's ability to understand concepts, both those obtained through interaction with the environment and concepts obtained from formal education. The conceptions of students that are different from what the experts agree on are called misconceptions or misunderstandings. Misconceptions of students that appear continuously will interfere with the formation of scientific conceptions and result in learning problems that can affect student learning outcomes. Therefore it is necessary to analyze the misconceptions of students. One of the diagnostic tests that can be used to analyze misconceptions is a two-tier multiple choice test or also known as a two-tier multiple choice, where the first level is the question being tested while the second level contains the reasons for the answer to the first level. This study aims to analyze misconceptions and determine the percentage of students' misconceptions on hydrocarbon material using descriptive methods. The subjects in this study were 27 students of class XI IPA 2 in SMA Pertiwi 1 Padang. The research instrument was a Two Tier Multiple Choice diagnostic test by dividing students' conceptual understanding into the categories of conceptual understanding, misconception, and conceptual misunderstanding. The results showed that the percentage of students' conceptual understanding in the concept understanding category was 32%, misconception was 34%, and did not understand the concept by 35% on hydrocarbon material. Students' misconceptions on hydrocarbon material at SMA Pertiwi 1 Padang were categorized as moderate

Tanah Datar Regency is known as one of the abundant fruit-producing areas of Kolang-Kaling. According to an interview by the PKM team with one of the heads of the women farmer groups, it was revealed that every week as many as 3 tons of Kolang-kaling fruit can be harvested. However, they only process 10% traditionally (boiled, peeled, and sold). The community does not have sufficient competence to apply technology in processing these plantation products into ready-to-eat food. As a result of the agreement with the two Cempaka Mekar and Teratai Women's Farmer Groups, also with the approval of the village head , a community partnership activity was agreed upon for these two farmer groups. With the aim of increasing the competence of women who are the target of activities in the application of technology for processing kolang-kaling fruit . Increasing competence is expected to have an impact on the welfare of the target community. In order to achieve the objectives, a problem-based workshop model was chosen, where the workshop activities were conducted based on partner problems, with an andragogical approach

This study aimed to utilize cassava processing liquid waste into biodegradable plastic with glycerol as a plasticizer. This experimental study varies the amount of glycerol: (0, 1, 2, 3, 4, and 5) mL. The resulting biodegradable plastics were analyzed for physical properties consist of (water content and degree of swelling), mechanical properties consist of (tensile strength, elongation, elasticity), biodegradation, and structural properties. Fourier Transform Infra-Red and x-ray diffraction were employed for the studies. The results showed that the more glycerol added, the greater the percentage of water content and the degree of swelling were obtained. The optimum tensile of the biodegradable plastic was reached with 3 mL of glycerol, giving the strength of 27.49 N/mm2, elongation 0.107 N/mm2, elasticity 4.804 MPa. Biodegradable plastic with the addition of 5 mL of glycerol degraded up to 60.777%. The FTIR spectra showed almost the same peaks between plastics without the addition of glycerol and glycerol. Meanwhile, XRD data shows that the degree of crystallinity of plastic without glycerol is higher than that of plastic with the addition of glycerol.
